Product Manuals
When do I Replace a Fuser Maintenance Kit in the HP Color LaserJet 4550N Printer?
You should replace the Fuser Maintenance Kit installed in your HP Color LaserJet 4550N Printer, if any of the listed below warning messages or/and print quality issues appears.

• ‘’FUSER LIFE LOW <> ORDER KIT’’ – The built-in monitoring system has detected that the installed fuser maintenance kit is near the end of its useful life. A new fuser maintenance kit must be installed soon after the initial appearance of this warning message, in order to be avoided various print quality and/or paper feed/transfer issues.

• ‘’FUSER LIFE OUT <> REPLACE KIT’’ – The installed fuser maintenance kit has been exhausted. You must install a new fuser maintenance kit immediately after the appearance of the warning message on the control panel display.

• ‘’50.X FUSER ERROR’’ – The built-in monitoring system has detected a fuser hardware error. You should try to resolve the issue by restarting your HP Color LaserJet 4550N Printer. Please install a new fuser maintenance kit, if the issue persists. Please note that the letter ‘’X’’ will be replaced with a number from one to seven, which indicates the error type. All fuser hardware errors are listed below.

1. ‘’50.1 FUSER ERROR’’ – The fusing temperature is too low.
2. ‘’50.2 FUSER ERROR’’ – The installed fuser cannot reach the normal work temperature.
3. ‘’50.3 FUSER ERROR’’ – The installed fuser is overheating.
4. ‘’50.4 FUSER ERROR’’ – The built-in monitoring system has detected a faulty fuser unit.

6. ‘’50.6 FUSER ERROR’’ – Fuser hardware error (Heater).
7. ‘’50.7 FUSER ERROR’’ – Fuser hardware error (Motor).

In some cases, the fuser maintenance kit must be replaced even if there are no warning messages displayed by the built-in monitoring system. All of the listed print quality issues could be caused by a faulty, damaged, or exhausted fuser unit. Please make sure that the print quality issue has not been caused by an incorrectly installed, exhausted, or damaged toner cartridge or imaging drum.

o Black lines
o Toner smear
o Irregular streaks
o Non-adhering toner
o Repetitive defects

Please note that you can check the status of the installed fuser maintenance kit at any time by printing a ‘’SUPPLIES STATUS’’ page. You should follow the instructions given below to install a new fuser maintenance kit in your HP Color LaserJet 4550N Printer.
How to Install a Fuser Maintenance Kit in the HP Color LaserJet 4550N Printer
The Fuser Maintenance Kit includes several consumable components. The replacement procedure for each of these consumable components is included separately below. Please follow the execution order strictly.

How to replace the Fuser Unit

Initially, you must turn the laser printer off, and wait about 10 minutes for the system fans to stop running. Then, you must unplug the power cord of your HP Color LaserJet 4550N Printer. Once you have unplugged the power cord, you must wait at least 30 minutes for the installed fuser unit to cool, and then open the rear door of the laser printer. After that, you must detach the straps from the rear door by squeezing their latches, and then rotate the lock release levers of the used fuser unit upward 90 degrees. Now, you must remove the used fuser unit from the laser printer by carefully pulling it towards you, and then unpack the new component. In the next step of the replacement procedure, you must insert the new fuser unit firmly into the printer, and then rotate the two blue levers down, in order to lock the new component into place.

How to replace the Air Filters

Once you have installed the new fuser unit, you must remove the two used air filters, which are located above the fuser unit, and then clean the fan areas. After that, you must unpack the new air filters. Now, you must insert the unpacked new air filters into the corresponding slots, and then reattach the support straps to the rear door of your HP Color LaserJet 4550N Printer. In the next step of the replacement procedure, you must close the upper rear door of the laser printer, and then proceed with the installation of the next component of the new fuser maintenance kit.

How to replace the Paper Rollers

In the first step of the replacement procedure, you must pull the lower paper tray (Tray 2) out of the HP Color LaserJet 4550N Printer, and then locate the used paper roller in the top of the lower paper tray compartment. After that, you must remove the used paper roller by sliding to the right while squeezing its tabs, and then unpack the new component. Now, you must slide the unpacked new paper roller onto the spindle until it clicks into place, and then open the cover, which is located inside the lower paper tray (next to the second paper roller). In the next step of the replacement procedure, you must remove the used paper roller (installed in the lower paper tray) by sliding it to the left while squeezing its blue tabs, and then insert the new paper roller onto the spindle until it clicks into place. At this stage of the installation, you must close the cover inside the lower paper tray, and then insert the lower paper tray back into the laser printer.

Final steps

Once all paper rollers are installed, you must plug the power cord in, and then turn your HP Color LaserJet 4550N Printer on. After that, you must wait until ‘’READY’’ is displayed on the printer control panel, and then navigate to the ‘’RESETS’’ menu by pressing the [Menu] button. Finally, you must navigate to ‘’NEW FUSER KIT, SELECT IF DONE’’ by pressing the [Item] button, and then press [Select].
